fo alli whom it may concern..-

Be it know-amat I, G. J.- NoLjrY, ofthe cty, county,an d. State of New York, have in- Een and I'do hereby v tleela're that the following is a full,. clear,and exact' description of the same, reterencebeijngmd to the accompanying drawings, making a part of` this specification, .in which-'- Y Figure l represents 'a perspective view of 'my invention.l

Fig. 2 isa longitudinalvertical section. of the same.v planor top view lof the lower or movable part of the valve; -Figa isa sectional view ofboth parts V'of the valve.

Similar lettersof reference .indicate corra,

spending parts in the several figures. This invention `relates -particularly to the means employed for the'purpose otl regulatingv the supply-.ef ink to for this purpose is dia-rubber, or other suitable material, fitted 1nicely into the lower end ofthe ink-fountain, and providedwitha central channel from- V which-a s m'all the plug,

groove leads to 4the edge ot' lower end .of the ink-fountain, which is provided with a hole vnear the edge,rand the face ot' which tits closely upon the faceof the movable plug in such a manner that by `turning said plug in one direction the groove in the face of the same and the .hole in the partition can be made to register, andthe in k isv allowed to flow to the pen, or by turning the plug in the opposite direction the groove in itsitac'e is moved from under the hole, and the supply of ink is stopped.

To enable others skilled in the art to make, use, and construct my. invention. I will proceed to describe it.

A represents a tube, made of metal "or any other suitable material, and provided ,with a stopper, a, at its upper end, so that by removing said stopper access can be had to its i1:- terior. This tube forms the ink-fount ain, and it connects at its lower end wit-ha short pipe, B, provided in its interior with a partition, b, which forms the stationary portion ofthe valve. The pipe B and tube A mayeither be made in two parts and fitted together sov as to 'form .aninlctight joint, or they may be made solid out of one and the same-piece of material. The pipeB extends beyond the partition b,

the pt n. The valve usedY composed of a plug of in,

anda stationary partition near the the opposite end of the as clearly shown in Fig. 2, -to form a socket for the movablepart ofthe valve. This part consists of a plug, '0, made of india-rubber or othersuitable material, and provided with a Icentral channel, c, from whicha small tube,

d,.leads tio the pen D. ,This plug is fitted 4nicely into thel pipe B or socket B,- and its face- 'forms an ink-tight joint against the face of the partition b. The partition b is provided with a small hole, e,near its circumference,

and a groove, f, -is cut into the face of the plug,

Vleadingfrom its edge to the central channel. By

turningsthe plug in the socketthe-groove can be made to register or not with the hole e in withthe hole, the ink ows freely to the cen- 'tral channel ot the plug andthrough it and the tube dto the pen buL when the groove does not register with the hole e the supply ot' ink is stopped. The position of the plug C is regulated by albutton, g, which projects through asot, h, in the socket B, so that it can be easily turned from one side tothe other.- 'This slot extends over an arc of' about one hundred and eighty degrees, and it is so arranged that when the button strikes one end ot' the saine Vthe lgroove f registers with the hole e, and when the button is turned to same the supply ot ink is stopped. The outer end ofthe plug O 4is slightly tapering, to receive the pen-holder,

and it is so arranged that it will tit to holders ot'difterent construction. My fountain arrangement can thus be used with any ordinaryppen, and the pen can bef changed whenever it isl desirable. The whole deviceis exceedingly cheap, andsimple in its construction, order.

AWhat I claim as new, and desire to secure by- Letter's Patent, is l 4 A fountain pen provided with a movable plug, (J, which has a central channel, c, and groovef, and works in the socket B, against the partition b, whichis provided with a hole, e, substantially in themanner herein specified,

and itis not liable to get out of sol that by turning the plug inthe socket the' supply of ink to the pen can be regulated.
